I've tried changing the cursor to software. I can get 1440x900 resolution (native for my screen) with the Nvidia drivers (6111), but the flicker has not gone away. DVD playback works until the first flicker, then video disappears after that although audio continues.

I've also tried the ignore edid option. When I use it, I get a virtual resolution of 1440x1024- I find that exceedingly strange.

I have the problem on my zd7000 also. I tried all the ideas found here and elsewhere, none worked. Finally I saw a suggestion to enter a screen geometry that was less that 1024x768,
then return to 1440x900 (ie, CNTL-ALT-KP_Subtract, CNTL-ALT-KP_Add). Added
a 800x600 modeline, the tried the size flip-flop, and it WORKED!
